Abstract

An electronic device is provided which executes a function useful in that place without a user in possession of the electronic device being intentional, and which does not receive a signal without providing a special setting if the function is not useful even if the place and the device are the same. There are an electronic device A and an electronic device each having a human body communication function. In a case where a user is holding the electronic device A, the electronic device B outputs a control signal for causing the electronic device A to execute a function aimed to eliminate a danger or an annoyance to the surroundings occurring because of holding it, whereas, due to the fact that the user has the electronic device, the electronic device A receives the control signal irrespective of the user'"'"'s intention and executes a function based on the control signal.
